HEADLIGHT.

SPECIFICATION forming part of Letters Patent No. 646,615, dated April 3,1900.

Application filed December 7,1899. Serial'No. 739,536. (No model.)

To all whom it"may concern;

Be it known that I, HENRY J. ALLEN, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented certainnew and useful Improvements in Locomotive-Headlights; and I 'do herebydeclare the following to be a full, clear, and exact deable othersskilled .in the art to which it appertains to make and use the same.

- My invention relates to improvements in locomotive-headlights; and itconsists in the novel combination and arrangement of parts,

scribed and claimed.

In the drawings, Figure l is a top plan view of my complete invention,showing its connection with the locomotive; -and Fig. 2 is a side viewofthe same. I,

The object of my invention is to construct a simple and practicallocomotive-headlight or one that may be moved or adjusted in such aposition as to throw the light departed therefrom in any direction andis especially adapted to be used when the locomotive is about toapproach a curve in the track, wherebythe light from the headlight maybe made to follow the track or curvature of the same.

Referring to the drawings, 1 represents the usual boiler of thelocomotive, 2 the smokestack of the same, and 3 the cab, all of whichare of the well-known construction.

Fixed to the smoke-stack 2 of the locomotive or any other stationarypart thereof are brackets 4, which form suitable bearings for receivingthe projecting ends of a rod 5, fixed to the ordinary headlight 6,whereby the latter is secured in a pivotal manner to the locomotiveinstead of rigidly, as heretofore. Projecting from the opposite sides ofthe headlight 6 are two arms 7, to which are secured one end of theropes or rods 8, the opposite ends of the latter passing throughopenings 9, formed in the cab 3 of the locomotive and attached to thelever 10 on either side of its pivotal connection, the said leveradapted to be operated by the engineer, fireman, or other attendantlocated within the cab of the locomotive, the said lever 10 beingpivotally connectedto a projecting bearing 11, to which are secured twofiat springs 12, the free ends of which cooperate with said lever oneither as will be hereinafter more particularly demaining parts, flatsprings 13 are employed, which in the present instance are attached tothe smoke-stack 2 of the locomotive, and havingtheir free endsnormallyin contact with the projecting arms or plates 14, fixed toandcarried by the headlight 6, which springs or either-one of the samewill yield sufficiently when the operating-lever 10 is pulled in eitherdirection'for the purpose of properly direct ing the light from theheadlight in the proper direction upon the track.

In operating the device, or when the locomotive is about to approach acurve in the track, the proper end of the operating-lever Inotwithstanding the irregularities of the rescription of the invention,such as will en-' is pulled by the attendant in the cab of thelocomotive, in which operation the headlight 6 is simultaneously turnedor operated, causing the light issuing therefrom to be properlydirected'upon the track in advance of the 10+ comotive or in anydirection that maybe desired bysaid attendant.

I do not limit 'myself to the precise con struction and arrangement ofthe parts as herein shown and described, as the same may be variedwithout departing from the nature of my invention, the principal objectbeing to construct a headlight for locomotives in such a manner that thesame may be properly turned in a suitable position to throw the lightissuing therefrom in adirection to follow the track in advance of thelocomotive.

As shown in Fig. 2, the lower bracket 4 is- I provided with anoutwardly-extending plate 15 and a support 16, depending therefrom andattached to the boiler 1, whereby the headlight 6 is supported rigidlyin the various positions which the same may assume, a roller 17 beingcarried by said projecting plate 15, upon which the lower surface of theheadlight rests.

Having fully described my invention, what I claim is- 1. In combinationwith a locomotive, of a pivoted headlight, springs cooperating with thelatter, for holding the same in a straight the locomotive, anoperating-lever pivotally secured to the sameabout its medial portion,springs fixed to said hearing or bracket, the free ends of whichcooperate with said lever, and rods or ropes connecting the latter andprojecting arms of the headlight, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
